TV out

TV out is a video card with output signal to a television related interface. TV output interface is currently mainly used to have three kinds. Using a VGA interface, VGA interface is the most cards have the interface type, but this requires TV with VGA interface can be achieved. Another is the composite video interface. Composite video interface uses RCA interface, RCA interface is currently the most widely used television equipment interface, almost every TV provides the interface, for video input. The last one is the most widely used, the output effect better S terminal interface.

At present, ordinary household display size does not exceed 19 inches, compared to the TV display screen size is much smaller, especially in the movie, play game, larger screen can give a strong visual enjoyment. While the larger displays the price of an ordinary user can bear, the display image is output to the television, it has become a good choice. TV output interface is currently mainly used to have three kinds. Using a VGA interface, VGA interface is the most cards have the interface type, but this requires TV with VGA interface can be achieved, with this interface is relatively less television, at the same time is a few more expensive products, popularity rate is not high. This method is generally not used, nor the people used to sense the video output. Another is the composite video interface. Composite video interface uses RCA interface, RCA interface is currently the most widely used television equipment interface, almost every TV provides the interface, for video input. Although the AV interface to realize the separation of transmission of audio and video, which avoided because the audio / video mixing interference caused the deterioration of the image quality, but because the AV interface transmission is still a luminance / chrominance ( Y / C ) mixed with the video signals, still need to display the luma / chroma separation and chroma decoder to imaging, the first hybrid separation process will result in loss of color signal, the chrominance signal and the luminance signal is also a great chance to interfere with each other, thus affecting the final output image quality. Using the AV interface to output the video card output effect is not very ideal, but it is on TV with interface, thus the interface by the user's favorite. At present, the output interface card products less, most provide output effect better S terminal interface. The last one is the most widely used, the output effect better S terminal interface.
